That is amazing. Gotta give all the credit in the world to a kid who won't be hobbled.
I recall a guy who made a device with 'fingers' that he attached to his back where the skin is sensitive. The device was connected to sensors that would trigger the device to tell him if there was anything solid ahead of him. He blindfolded himself for, IIRC, two weeks with this device attached and said he was developing a sense akin to sight.
